This research was the improvement of pressing process in the automotive industry that studied BRACE-FR PLR UPR HINGE part in H production line. Which found that the average time of the die setting process was 8.18 minutes per time and the average time of pressing process was 0.81 minutes per piece. Resulting the average production rate was 422 pieces per hour which did not achieve the production plan at 450 pieces per hour. Therefore, this research aimed to improve the working method to decrease the time of the die setting process and increase the production rate by using the work-study with 5W1H question technique, ECRS principle, and the principle of motion economy. Which designed the new working method for the die setting process and made the scrap conveyor in process 2 for the pressing process, including changing the new location of hand switches. The results of improvement showed that the average time for die setting decreased from 8.18 minutes per time to 5.51 minutes per time or 32.64% and the average production rate increased from 422 pieces per hour to 474 pieces per hour or 12.32%.
